Google Chrome problem...can you help?

I keep uninstalling and re-installing Google Chrome to fix this little problem....

Sometimes, checkboxes fail to appear on webpages. For example, I might be purchasing something online and have to check a box to agree to the terms of service....these check-boxes often are not there when they should be. This is a fairly new problem. For months Chrome worked well...then suddenly those checkboxed stopped showing up one day. My Adobe Flash player and Java are both up to date.

Anyone know what might be the problem?

A couple things I would suggest trying:
make sure you're using Chrome and not Chromium
Make sure you're using the latest version
If you're already using the latest version, try an earlier version
If none of this helps, try recreating the problem with no extensions enabled
